Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0020] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this invention are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product or device.

[0021] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0022] like Figures 1-3 As shown, a screen control device includes: a screen mounting base 100, a support part 200, and three telescopic members 300. The three telescopic members 300 are all disposed on the support part 200. In this embodiment, the telescopic direction of the three telescopic members 300 is preferably the same. The screen mounting base 100 has three mounting parts 110 arranged in a triangle; The drive end of the telescopic member 300 (the drive end of the telescopic member 300 is the end where the telescopic member 300 extends and retracts to drive the screen mounting base 100 to move; the telescopic member 300 can be composed of a push rod, etc.) is provided with a hinge member 400. The two ends of the hinge member 400 are a first connecting part 410 and a second connecting part 420, respectively. The first connecting part 410 is hinged to the telescopic member 300, and the second connecting part 420 is hinged to the corresponding mounting part 110.

[0023] Based on the above structure, the carrier 200 is installed on the vehicle, and the screen is installed on the screen mounting base 100. The carrier 200 is hinged to the screen mounting base 100 through three telescopic members 300. By controlling the telescopic cooperation of the three telescopic members 300, the hinge member 400 is driven to move, thereby controlling the screen mounting base 100 to adjust its tilt and left and right orientation. This increases the flexibility of screen position and angle adjustment, thereby meeting the viewing needs of different users and obtaining a better viewing experience.

[0024] It should be noted that, depending on the usage requirements, the above-mentioned hinge is one of the following: rotary hinge, ball hinge, universal hinge, and cylindrical hinge.

[0025] like Figures 2-4As shown, the second connecting part 420 is connected to the mounting part 110 by a cylindrical hinge, and the first connecting part 410 is connected to the telescopic member 300 by a ball joint, so that the screen mounting base 100 can rotate relative to the second connecting part 420 and the first connecting part 410 relative to the telescopic member 300 according to their respective degrees of freedom. Since the first connecting part 410 and the second connecting part 420 are integrated, the manufacturing difficulty is reduced, and the requirements for the shape of the drive end of the telescopic member 300 are lower.

[0026] like Figure 3 and Figure 4 As shown, the telescopic component 300 includes a power component 310 (including but not limited to a motor), a screw 320, a nut 330, and a connector 340. The screw 320 is rotatably mounted on the bearing portion 200. The power component 310 drives the screw 320 to rotate. The nut 330 is sleeved on the screw 320 and threadedly connected to the screw 320. The nut 330 is connected to the connector 340, and the first connecting portion 410 is hinged to the connector 340. Thus, by driving the screw 320 to rotate through the power component 310, the nut 330 moves along the axial direction of the screw 320 (in order to limit the rotation of the nut 330 and make the nut 330 only move in a straight line, a limiting structure (including but not limited to a limiting track, etc.) is provided on the bearing 200 to limit the rotation of the connector 340), thereby driving the connector 340 to move towards or away from the screen mounting base 100, and thus driving the screen on the screen mounting base 100 to move.

[0027] Further optimizations include, for example Figure 3 and Figure 4 As shown, in this embodiment, the connector 340 is tubular and is sleeved on the nut 330. Thus, by sleeved on the nut 330, the tubular connector 340, which is also sleeved on the screw 320, effectively seals the screw 320 and nut 330, preventing foreign objects from coming loose from the screw 320 or nut 330. Figure 5 As shown, in order to guide and restrict the movement of the connector 340, three limiting rails 210 are provided on the bearing part 200. The three connectors 340 are slidably disposed at the three limiting rails 210 respectively. The setting of the limiting rails 210 not only plays a guiding role, but also supports the connectors 340, making the structure more stable. In this embodiment, the limiting rails 210 are formed by cavities opened on the bearing part 200. The shape of the cavity is adapted to the shape of the connector 340. That is to say, if the connector 340 is a square tube, the cavity is cuboid (at this time, there is no need to set the above-mentioned limiting structure). If the connector 340 is a round tube, the cavity is cylindrical (at this time, a limiting structure is required to limit the rotation of the round tube, so as to limit the rotation of the nut 330).

[0028] likeFigure 4 As shown, a hinge seat 341 is provided at one end of the connector 340 near the bearing portion 200. The first connecting portion 410 is ball-hinged on the hinge seat 341. The first connecting portion 410 is installed through the hinge seat 341, making the relative movement more stable.

[0029] Further optimization is that, in this embodiment, the line connecting the axes of the three screws 320 is preferably triangular (most preferably isosceles triangle). Similarly, the line connecting the positions of the three mounting parts is also triangular, meaning that the mounting parts correspond one-to-one with the axes of the screws 320. This ensures that the force distribution at the hinge point between the screen mounting base 100 and the telescopic member 300 is uniform, resulting in better stability. For this embodiment, a further optimal setting is that the axial direction of the cylindrical hinges of the two second connecting parts 420 located at the two base angles of the isosceles triangle is the first direction, and the axial direction of the cylindrical hinge of the second connecting part 420 located at the apex angle of the isosceles triangle is the second direction. The first direction and the second direction are not in the same direction (ideally, they are perpendicular to each other).

[0030] The screen control device provided in this application can increase the range and smoothness of the display screen rotation, avoid the motion stuttering and unsmoothness caused by using only single-degree-of-freedom hinges, improve the user experience, and make the connection between the screen mounting base and the telescopic component more stable and buffered. While improving the overall rigidity of the screen control device, it also improves the flexibility at the connection position of the screen mounting base. When facing a certain degree of vibration and impact, the triangular distribution structure and hinge structure can reduce the amount of sway of the screen mounting base, thereby weakening the vibration of the display screen, improving the vibration resistance reliability of the device, and preventing device damage.

[0031] This application also provides a display device, which includes a display screen 500 and a screen control device, wherein the display screen 500 is mounted on a screen mounting base 100.

[0032] This application also provides a vehicle, which includes a display device. The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that are directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
